Analyzing device

A device for and a method of analysing a sample, comprising: a sample positioning unit (1) for positioning a sample (3); a radiation generating unit (16) for providing at least one beam of electromagnetic radiation to each of first and second surfaces of the sample (3); an imaging unit (23) for providing at least one image from radiation transmitted through each of the first and second surfaces (3a, 3b) of the sample (3); a detector unit (25) for capturing the images provided by the imaging unit (23) and generating signals corresponding thereto; and an analysing unit (61) for operating on the signals received from the detector unit (25) and generating signals representative of the three-dimensional distribution of at least one component in the sample (3).
